Simple high-band record modulation circuit in 8MM video tape recorder

摘要

A record modulation circuit having a first frequency deviation amount determiner for determining the frequency deviation amount suitable for a normal recording mode, and a second frequency deviation amount determiner for determining the frequency deviation amount suitable for a high-band recording mode, wherein an 8 mm video tape recorder for normal recording can perform a simple high-band recording. The record modulation circuit is hereby enabled to perform a normal recording operation and a high-band recording operation with only a normal recording IC.
